无法使用crfsuite的C++ API编译一个非常简单的Tagger示例

我已经从源代码(https://github.com/downloads/chokkan/crfsuite/crfsuite-0.12.tar.gz(正确安装了crfsuite。 但是当我尝试编译一个非常简单的代码时，似乎我错过了一些东西。

这是代码：

#include "crfsuite.hpp"
using namespace CRFSuite;
int main(int argc, char *argv[]) 
{ 
Tagger tagger;
}

下面是要编译的命令行：

g++ -L/usr/local/lib -I/usr/local/include -lcrfsuite tagging.cpp

和错误：
